3PAR Host Explorer User’s Guide
4.8.1 InServ Storage Server Upgrades and Enclosure Devices
If you upgraded to 3PAR InForm Operating System version 2.3.1 from a previous release, you
must consider the following notes about LUNs with ID 254.
■ If you had a LUN with ID 254 before you upgraded to 2.3.1, the host persona for the host is
set to the Generic-Legacy persona number 6 during the upgrade process. The port persona
number must be reset to Generic persona number 1 before the Host Explorer can
communicate with the InServ Storage Server.
1) Use the InForm Command Line Interface (CLI)
sethost –persona 1 <host name>
command to set the host persona number to 1.
2) Use the
controlport offline command to take the InServ Storage Server port
the host is connected to offline.
3) Use the
controlport rst command to reset the InServ Storage Server port
connected to the host.
Alternatively, if you reboot the host after resetting the persona number as described in
step 1, the Host Explorer automatically discovers the enclosure device on LUN ID 254 and
sends the information to the InServ Storage Server. For more information about CLI
commands, see the 3PAR InForm OS CLI Administrator’s Manual.
■ If you add a host after you upgrade to 2.3.1, the host persona number for the host must be
set to 1. For more information about creating and modifying hosts, see the 3PAR InForm OS
CLI Administrator’s Manual.
You can also use the InForm Management Console to configure and administer hosts
connected to the InServ Storage Servers. For more information, see the 3PAR InForm OS
Management Console Online Help.
